The plaza at 801 Grand Avenue, originally constructed in the 1980s, suffered from water leakage into the underground parking garage, paver movement, and paver deterioration.  The 31,000 sq ft plaza is a concrete slab with waterproofing covered primarily with granite pavers on a mortar setting bed.  The plaza also featured planters, concrete drive ramps, and concrete sidewalks.  SGH investigated the causes of leakage and paver deterioration, recommended a remedial program, and designed repairs.
